碩士 === 國立臺灣科技大學 === 化學工程系 === 102 === In this thesis, we synthesize the derivatives of BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s- indancene), and apply these derivatives in dye sensitized solar cells. Use the conjugated system of Donor-π-Acceptor (D-π-A) on the design, and BODIPY play the role of π-conjugation system, bounding with same donor is bis-(4-methoxy-phenyl)-phenyl-amine moiety, and acceptor substituent is cyanoacrylic acid on the β-substituent of BODIPY. On the other hand, we synthesize the derivatives of 4,4-dihydroxyaryl-diaza-s-indacene and for the first time apply these dye in dye sensitized solar cells. These compounds are characterized by 1H NMR, 13C NMR, mass spectrometry, their absorption spectrum were estimated by UV-visible spectrometer, and their energy level of HOMO and LUMO in solution and adsorb on TiO2 were estimated by cyclic voltammetry and low-energy photoelectron spectrometer, respectively, use density functional theory and time-dependent density functional theory to imitate the orbital and energy levels of HOMO and LUMO, and apply in DSSCs. The highest power conversion efficiency in this thesis is MPTT ( Jsc = 16.04 mA / cm2, Voc = 0.61 V, FF = 0.65, η = 6.43 % ).
